To all whom 'it may concern:

Be it known that I, HONARE MORIN, a citizen of Canada, residing at Auburn, in the county of Androscoggin and State'of Maine, have invented certain new and useful Im-v provements in Sole-Leveling Machines; and that I do hereby declare the following to be a full, clear, and exact description of the invention, 'such as will enable others skilled inthe art to which it appertains to make f and use the same.

This invention relates to improvements in sole leveling machines, and has for one of its objects to provide an improved mounting for the leveling roller permitting floating movement of the latter under tension as it traverses the surface of the shoe sole.

Another object of the invention is the provision of a novel and conveniently controlled driving mechanism for the reciproeating leveling roller carriage.

A still further object is the provision of an improved shoe and last `support embodying4 novelk features of construction permit# ting the lasts andl toe supports to be adc Vjusted, longitudinally of the machine and vertically to accommodate shoes of various sizes.

With these and other objectsin view, the invention consistsin the novel construction, y

combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which: I

Figure 1 represents a side elevation of the improved machine,

Fig. 2 represents a front elevation thereof,

Fig. 3'represents an enlarged detail view in side elevation ofthe frontend of the leveling roller carriage and the slice-supporting devices,

Fig 4 represents 'a horizontal sectional view on the line 4-1 of Fig. 1,' j

Fig. 5 represents a 4detailsectional view through the support yfor the leveling roller,

Fig. 6 represents a vertical detail sectional n View on thefline 6 6 `of Fig. 1,

Fig. 7 represents a fragmentary sectional view on the line 7-7 of Fig. 5, and

Fig. 8 represents a vertical sectional view through the toe-supporting pad for the shoe.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 10 indicates generally a'supporting frame structure forthe machine,- which includes a `horizontally disposed Ltable or bed plate 11, provided with a longitudinally extending slot 12 `receiving the base member 13 carrying the toe-supporting pad 14 for the toe ofthe shoe. The base' member 13 isslidable longitudinally in the is mounted for vertical adjustment upon a screw 16, threaded in a vertical recess 17 formed in the base member 13 and secured in vadjusted position by a hand wheel 18, having an internally threaded aperturetting the screwthreads of the screw 16, whereby the latter is rigidly secured in adjusted position with relation' to the base member. y v

In front of the toe pad 111 a vertically movable slide rod or bar 19 is iitted inca guide 2O carried by the table l1, and carries.

at its upper terminal a last-supporting pin 21, which is adjustable vertically with the bar 19. vThe lower terminal of the bar 19, which extends between and forwardly of the front supporting legs ofthe frame struc` ture 10 is provided with gear teeth 22, which mesh `with a pinion 23 rotatably supported on ashaft 2fl"journaled` in the front supporting legs of the.l frame structure. A hand lever l25 is rigidly connected with the shaft 24 and extendsupwardly alongside of the supporting `leg of the frame, terminating at a point'conveniently near the table 1 1. By oscillating the hand leverl 251 the gear wheel 23 isY actuated to elevate or lower the vlastsupporting; rod 20, and the lever'is locked in adjusted position by a preferred type of locking device, designatedA generallyby the numeral 26. c

A pairy of opposed levers 27 is pivotally' mounted at 28 to the frontend of the table 11 and carry a pairof heel-clamping platesv 29, which terminate. ladj acent the last-supporting p1n`21l and are designed to firmly clamp ,the heel portion of the shoe 30.v VThe slot` groove12, and is secured in adjusted j position, to'accommodate Vshoes of varying lengths, by a lock screw 15,. The toe pad 14:' 65

lower'terminals of the levers 27 are pivotally i i connected with the upper terminals of a second pair oflevers y31, which are pivotally supported'atl 32 upon the frame lstructure 10, and are'connected at theirlower terminals by a pair of curvedlinks 33'with a connecting rod 34. A foot actuated pedal 35' is pivotally supported by a depending bracket arm 36 carried by the frame structurev lO andispivotally connected at 37 with the lower terminal of the connecting rod 34, at a point forwardly of the pivotal connection between the pedal and the supporting arm 36 therefor, whereby when the pedal is depressed, the levers 27 are swung so as to cause the clamps 29 to firmly engage the opposed side portions of the heel of the shoe 30.

A substantially U-'shaped screw Supporting member 38 is pivotally secured at its opposite ends to the front terminal of the table 11, as indicated at 39, and the web portion thereof is provided with an internally threaded aperture receiving a screw 40, carrying lan adjusting hand wheel 41 at its upper terminal and a heel-engaging block 42 at its lower terminal, adapted, as the screw 40 is advanced, to engage and levelv the heel portion of the shoe.

The upper part of the frame structure 10 is provided with a horizontally disposed and longitudinally slotted guide or support 43 for the reciprocable carriage 44, having',

gear teeth 45 formed in the lower surface thereof. The front terminal of the carriage 44 is hingedly connected at 46 with a frame .47, which is movable with the carriage 4 4 during its reciprocating movement and is extended position. As is clearly evident by reference to Fig. 5 the yoke 52 is substantially U-shaped and the web portion thereof is formed with an arcuate slot 53, receiving theheaded terminal of a rod 54, permitting the yoke 52 to oscilla-te freely in the front end of the pivoted frame 47.

The apertured end 55 of a presser rod 56 is confined between the web portion of the U-shaped yoke 52 and a washer 57 engaged underneath the spring 51, and the rear terminalv of the presser rod 56 is connected by a joint 58 with a spring pressed plunger 59, extending within a recess 60 formed in the carriage 44 and engaging an expansion spring 61 located therein.y The tension of the springyl normally tends to tilt the pivoted frame 47 forwardly upon its pivotal axis 46. A shaft 62 is journaled in the par-` allel terminals of the U-shaped yoke 52 and supports the concaved leveling roller 63, which is confined between said parallel terminals. The vertical movement of.V the opposed terminalsof the roller 63 incidentv to the oscillation of the roller, over the irregular surface of the shoe sole is guided by vertically disposed slots 64 formed in the vertically movable guide blocks 65 slidably mounted in vertical grooves 66 formed in the side members of the pivoted frame 47. The tension of the spring 51 normally acts to maintain'the roller 63 in rolling contact with the surface of the shoe sole, and by properly adjusting the screw 49 the tension' may be varied as desired.

To manually increase the pressure eX- erted by the roller 63 against the shoe sole or to manually adjust said roller to maintain it in rolling contact with the shoe sole, an angular handle 67 is connected with the yoke 52, and is extended laterally and forwardly of the frame 47 into convenient reach of the operator of the machine.

The lower terminal of the portion of the pivoted frame 47 supporting the leveling roller 63 is provided with inwardly directed fingers 70, which slide upon relatively sta tionary guides 71 carried by the frame structure 10. The guides 71 project forwardly on opposite sides of the toe pad 14 and are curved downwardly at their front terminals, as indicated at 72, to permit the frame structure 47 to swing downwardly under the influence of the spring 61 as the roller 63 rolls over the comparatively low heel portion of the shoe 30. The ingers are confined beneath guide anges 74 carried by and adjustable with a vertical extension 75 carried by the adjustable toe pad supporting base member 13. As clearly shown in Fig. 3, the guide Hanges 74 terminate at a point rearwardly of the toe of the shoe 30, so as to release thespring actuated frame 47 prior to the engagement of the leveling roller 63 with the shoe sole.

Asstated, the reciprooable carriage 44 is provided with downwardly projecting gear A teeth 45, and these teeth mesh with a gear segment 76 supported upon la shaft 77, which latter is journaled in bearings 78 provided in the frame structure 10. A gear wheel 79 is also non-rotatably secured to the shaft 77 and meshes with a relatively small pinion 8O carried by a shaft 81, which latter is mounted in relatively stationary bearings 82 carried by the frame structure 10.

The rear portion of the frame structure 10 underneath the carriage 44 is provided with a horizontally disposed guide 83 supporting a longitudinally movable frame structure consisting of a pair of spaced sections 84, which are connected by the inverted U-shaped reinforcing bar 85 and are arranged in spaced relation to each other to accommodate the bearing 82 of the shaft 80. The terminals of the frame sections 84 abut shock absorbing springs 86 housed in recesses 87 provided at the terminals of the guide or support 83.

Shafts 88 and 89 are mounted in bearings 90 and 91 carried by and movable with the framesections 84 and the shaft 88 carries-a friction wheel 92, which, when the frame 84 movedrearwardly,'engages and drives" the friction wheel 93 carried by the shaft 81.- The f shaft 89 supports a friction wheel 94,4

which, when the frame 84, is moved forwardly, engages and drives the friction. wheel 93 and shaft 8l in the direction opposite to that in which it is driven Ywhen 'engaged by the friction 'wheel 92.

The frame sections 84v are rigidly*` connected with 'the upper terminalsof a depending V-shaped member-V 96, whichsupports an idler shaft 97 "carrying the rela-- tively'non-rotatable pulleys 98 and 99. The pulley '98 is connected by a belt '100 with the "pulley 101 carried by the shaft 88, and the'other pulley 99 carried by the intermediate shaft 97 is'connected by a belt 102 with a pulley 103 lcarried by the shaft 89.- The belt l102 is crossed, asl clearly shown in Fig.

l1, wherebythe shafts 88 and 89 are driven in opposite directions. AdriveshaftA 104 isr mounted bearings 105 carried bythe frame section v84, and is connected by a belt y 106I with the pulley 103.' i The4 pulley 107,

vcarried'b'ythe'shaft 104,is designed for connection witha4 suitable` drive shaft (not shown), whereby'the machine is operated.

From th'efo'regoing, itis evident that inoperation the shoe last is supported upon the `supporting piny 21, andthe latter is elevated' to the desired position by proper adjustment of the hand lever 25.YK The toe pad 14is subsequently' adjusted vertically and longitudinally to assume thecorrect rposition to sup'- "port the toe of the shoe, and'by ldepressing the pedal 35` the clamping members 29 are caused to rmly grip the heelportion of the shoe.l Assuming that the drive pulley 107 lis rotated in .thedirection of the arrow in Fig. 1, Athe movable'frame 84,V ismoved rear'- wardly so as to engage the'friction wheelv 92 withthe `frictionwheel 93, so as to cause the`r carriage 44 to move forwardly. For conveniencey in 'adjus'tingj the frame ,84,v an arm 109Y vis' rigidlyy connected therewith 'and .is

pivotaly; attached at its: forward extremity with an arm 110,y carried by a shaft 111 on which is Ymounted a hand lever '112.` VThe vvrotary lmovement of the drive pulley 107 is transmitted to rthe carriage44 through the belts 106, 102,100, friction wheels 92 and 93,

gear wheelSfS' and 7 9' and finally through thegear segment 7 6 tothe toothed portion 45of the carriage.` During the forwardv movement of thecarriage, the leveling roller 63 rolls over the surfacey ofthe shoe sole 30, thereby effectivelyl leveling the latter.

The roller 63 andits shaft-62 are retainedin V rolling Contact with the shoe sole by the ten-y sion `of the spring 51,'Vand the shaft 62v'is permitted to oscillatein order to maintain the roller in snug engagement with the surface of thesole bythe sliding contact of the shaft* with the groovesi64 :and the slidabley mounting of the supporting blocks 65.
